In Madhya Pradesh, the efforts are being made towards realizing Prime Minister Narendra Modi’s dream of Waste-to-Wealth, to emerge as a role model for other major states of the country. Under the leadership of Chief Minister Shivraj Singh Chouhan, the state has taken remarkable steps towards self-sufficiency in waste management. One key initiative is the production of bio gas and bio CNG from urban wet waste, contributing to both environmental sustainability and economic growth.
Process of making bio gas and bio CNG
To create bio gas and bio CNG from wet waste, the first step is separate waste collection. Madhya Pradesh has taken a significant stride in this direction, with 100 out of 5423 garbage collection vehicles focusing on gathering waste from residential and public areas.
In 2018-19, the state established bio gas production units capable of processing 20 tonnes per day from the Chauithram vegetable market in Indore and 15 tonnes per day in Kabitkhedi. These units required an investment of Rs 14 crore 5 lakh through public-private partnerships. Additionally, bio gas units with a combined processing capacity of 127 metric tons per day were set up in Indore, Dewas, Ujjain, and Bhopal. Bhopal also introduced 5 mini units to process 17.5 metric tonnes of wet waste. Ujjain took the lead in generating electricity from bio gas, while Dewas embraced private sector participation with a small-scale unit.
In the second phase, the Indore Municipal Corporation established the Gobar Dhan Bio CNG plant at Dev Guradia, increasing a processing capacity of 550 metric tons. This project operates on a public-private partnership model with Environmental Infrastructure and Services Limited and German company Proveps. From this unit, approximately 17,500 kg of bio-CNG and 100 tons of high-quality compost are produced. Moreover, Bhopal is currently constructing a bio-CNG unit with a capacity of 400 metric tons per day in Adampur, with an investment of Rs 80 crore. A PPP contract was signed with Bhopal Enviro Private Limited in April 2022 to ensure the unit becomes operational within 15 months.
Madhya Pradesh plans to replicate Indore’s successful model in other urban areas, both large and small. In Gwalior Municipal Corporation, efforts are being made to produce bio gas from the dung obtained from 7,000 cowsheds in garbage processing plants. Apart from this, efforts are on to create small projects for bio gas production from wet waste in Hoshangabad, Sehore, Vidisha, and other major cities.
Madhya Pradesh’s Waste-to-Wealth initiative is a testament to its commitment to sustainable waste management and environmental conservation. By transforming wet waste into bio gas and bio CNG, the state not only reduces its environmental footprint but also generates valuable resources, paving the way for a cleaner and more prosperous future.
